Very good product, in a thick layer of mandatory mesh because it will crack, it can be mixed with any commercial watercolor or powder, it just needs a good stirring (it is better to add the pigment before mixing it with the catalyst because afterwards the material becomes slightly thicker), you can also make it thinner and easier to work with by adding a minimal amount of water. Also, if white cement is mixed with black color, the shade will turn into a beautiful cyan color before it darkens too much. It hardens well after at least 24 hours. Try using a brush dipped in water-diluted cement (to make it like a thick paint) for areas where you want to spread the material better and a trowel or spatula won't work
